I recently noticed that a story map I published earlier in the year is throwing an error for public viewers. I can still login to view and edit the story and have republished it. This was previously published with no public viewing issues. When I select 'update sharing settings' I get an error but the message is vague and I'm not sure what the issue is. All of the layers and maps referenced in the story map are public. I'm not sure how to troubleshoot, any suggestions?
